switching oil
i currently run mobil 1 in my stang. I was wondering if it would hurt the motor if i switched back to conventional motor oil. the mobil 1 site says that you can mix the mobil 1 and regular oil because the mobil 1 has a regular oil base instead of a synthetic base.... so basically what i got outta that is that mobil 1 is regular oil with additives. Any way would it hurt my motor if i switched back to regular oil??
